Senior UX/UI Designer

Our mission is to build the intelligent brain for every food factory, with the only AI-powered factory management software for the food industry, bringing together machines, sensors, software, and people.

Profitable from day one, we’ve recently secured a record-breaking €11M Seed Round, the largest in Portugal’s history, to take our mission global. And we’re getting there, because today over 25% of all meat production in Portugal is already managed by BRAINR.

Along the way, we’ve been recognized as the Best Factory Digitization Solution at Food 4 Future in Spain, selected for EUROPA’s 100 most promising startups, and named a Top Cloud-Based MES Solution by Manufacturing Tech Insights.

What sets us apart isn’t just the tech. It’s the people. Our leadership team combines deep industry know-how with world‑class tech expertise, giving you the chance to learn and grow faster than anywhere else.

The mission is massive. The ambition is real. And we need talent like you to bring our vision to every food factory on earth.

This is a high‑impact role where you’ll take ownership of design across the product, balancing user needs, technical constraints, and business goals. You’ll help us move from functional to exceptional – transforming complex industrial workflows into intuitive, scalable interfaces that are loved by users.

You’ll work closely with engineers, product managers, and implementation teams to ensure design is embedded into every step of our process, and you’ll help shape how we scale design in the years ahead.

5+ years of experience in UX/UI design, ideally in B2B or SaaS products

Strong command of Figma and experience building and managing design systems

A portfolio that shows a clear design process, thoughtful UX decisions, and clean UI

Experience conducting user interviews, usability testing, and applying insights
